Last year I tried to get to know the optical limits in terms of sharpness of my moderate equipment (Samyang 135mm tele lens in combination with an ASI178MM uncooled) for imaging DSO objects. The result is quite amazing, when the aperture is stopped down to F/2.8. The test object was Messier 16, containing the famous pillars of creation.
